LAST UPDATED April 21, 2025

Last week, Zwift launched a 6-week workout series featuring one fresh workout each week to help us “lock in consistency and keep up with your friends.” Dubbed Zwift Camp: Inside Out, this is effectively an updated version of the Spring Training series Zwift ran in 2024 and 2023.

The big idea, Zwift tells us, is to help Zwifters build fitness with effective indoor workouts so they’re stronger than ever as they head outdoors.

Here are all the details of this short series…

Getting Started

To register for Zwift Camp: Inside Out, click the large banner on the homescreen or the smaller card in the “Challenges” row. Then click “Register”, and you’re all set!

Workout Details & Schedule

Zwift Camp: Inside Out can be completed “on demand”, meaning you do the workouts and Hilltop Hustle route by yourself, whenever you’d like. Keep in mind the workouts scheduled for future weeks won’t be available until that week arrives.

The other option is to join the group workout events scheduled hourly each day at the top of the hour.

Regardless of how you choose to execute the workouts, you get your choice between the standard workouts (around an hour long) or “lite” versions (around 30 minutes long).

Stage 1 – Ramp It Up (April 14-20)

“This first session of Zwift Camp: Inside Out sets the tone for building a strong endurance base.”

Stage 2 – The Endurance Groove (April 21-27)

“With progressive blocks that challenge your ability to sustain effort, this session builds muscular endurance and mental focus.”

Stage 3 – Cadence In Control (April 28-May 4)

“Time to tackle intervals at varying cadences, training your body to adapt to different terrain and riding styles.”

Stage 4 – Surge Protector (May 5-11)

“Workout 4 is all about real-world challenges like breakaways and hill sprints—helping you build strength, resilience, and faster recovery.”

Stage 5 – Climb On (May 12-18)

“Get ready to alternate between steady efforts and surges, building strength and endurance while learning to handle varying gradients.”

Stage 6 – Hilltop Hustle (May 19-25)

“Wrap it up and put all your hard work to the test on Hilltop Hustle, a route featuring The Grade!”

Make-Up Days: May 26-June 1

If you missed a stage but want to make sure you complete all six, there is a make-up week at the end of the series. (Again, you can also do the workouts on your own whenever you’d like.)

Kit Unlocks

Riders will receive the Inside Out socks after completing one stage, the visor after completing three stages, and the 2024 Zwift Camp: Inside Out kit after completing all six stages.
